1. Tooth movement relative to the alveolar bone can be precisely described only by superimposing on fixed points in the bone. Implants are the best known way today. Over short-term studies laminagraphy and the use of bony trabeculations are also useful.

Tooth movement – clinical implications
International Orthodontics, 2010The tissue-based phenomena and the tissue interactions responsible for tooth displacement can be modulated by varying the intensity of the applied forces or by means of medicated molecules absorbed by the patient or prescribed by the orthodontist. However, harmful side-effects such as inflammatory root resorption or replacement resorption (ankylosis ...

American Journal of Orthodontics, 1984
Orthodontic forces can be treated mathematically as vectors. When more than one force is applied to a tooth, the forces can be combined to determine a single overall resultant. Forces can also be divided into components in order to determine effects parallel and perpendicular to the occlusal plane, Frankfort horizontal, or the long axis of the tooth ...

Prostaglandins and tooth movement
The European Journal of Orthodontics, 1984The effect of flurbiprofen, a prostaglandin cycloxygenase inhibitor, on tooth movement was studied using New Zealand white rabbits. Under general anaesthesia, springs were ligated between the lower first molars and incisors resulting in approximation of these teeth.

Orchestration of tooth movement
American Journal of Orthodontics, 1983Recent advances in the art and mechanics of delivering orthodontic forces have achieved greater precision and control of tooth movement. The exact mechanism by which these forces orchestrate tooth movement is not thoroughly understood. An accurate understanding and precise control over the factors responsible for initiating and carrying out the tissue ...

Critical Reviews in Oral Biology & Medicine, 1991
This article reviews the evolution of concepts regarding the biological foundation of force-induced tooth movement. Nineteenth century hypotheses proposed two mechanisms: application of pressure and tension to the periodontal ligament (PDL), and bending of the alveolar bone.

Clinical Dentistry Reviewed, 2017
The current concept of “pressure-tension” tooth movement is based upon reductionist explanations of parsed physiological processes that do not provide a cohesive understanding of clinically relevant tooth movement. The biology underlying accelerated orthodontic techniques have refocused attention on disruptions of tensional integrity of ...

The Journal of the American Dental Association, 1960
The three types of endogenous tooth movement are (1) the continuous eruption of teeth, (2) migration due to inherent weakness of the attachment apparatus, and (3) the adaptive movements of the teeth. Adaptive tooth movement is controlled by: (1) the contact relationships between adjacent and opposing teeth, and (2) the interaction of the components of ...

Piezoelectric Tooth Aligner for Accelerated Orthodontic Tooth Movement
2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018In this paper, we propose a device that can induce vibration to potentially accelerate the rate of orthodontic tooth movement and thus reduce the duration of the orthodontic treatment. This is accomplished by harmonically exciting a polyvinylidene fluoride (PVDF) piezoelectric actuators to generate vibration and hence generate cyclic loading at 30 Hz ...

Medication and orthodontic tooth movement
Journal of Orthodontics, 2019As any pharmaceutical substance may influence the events associated with orthodontic tooth movement, it is of importance for the clinician to be able to recognize any prospective patient’s history and patterns of medicinal consumption. This review presents the effects of various commonly prescribed medications on the rate of orthodontic tooth movement.
